/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 55988.508421 0.001249 0.21340 0.05268 0.96512 1 1.81116 0.18949 0.45290 0.04738 0.38649 0.08643 0.09639 0.02155 55988.511427 0.001758 0.18453 0.04199 0.98163 1 1.67121 0.15227 0.41901 0.03818 0.30838 0.06430 0.07746 0.01615 55988.574893 0.001031 0.30854 0.07936 0.94366 1 1.53837 0.19061 0.38338 0.04750 0.47465 0.10699 0.11854 0.02671 55988.576883 0.000959 0.23977 0.06022 0.98485 1 2.06780 0.22923 0.51070 0.05661 0.49580 0.11174 0.12219 0.02754 55988.579033 0.001191 0.22804 0.05681 0.96341 1 1.80826 0.19193 0.44159 0.04687 0.41236 0.09293 0.10053 0.02266 55988.581430 0.001206 0.25290 0.06377 0.98795 1 1.56474 0.18230 0.38367 0.04469 0.39572 0.08849 0.09756 0.02182 55988.583826 0.001191 0.22727 0.05668 1.00000 1 1.75778 0.19403 0.42892 0.04735 0.39949 0.08933 0.09756 0.02182 55988.586673 0.001656 0.14967 0.03623 0.98246 1 1.94058 0.17122 0.47441 0.04186 0.29046 0.06546 0.07091 0.01598 55988.590682 0.002353 0.20336 0.03650 0.99208 1 1.88866 0.14223 0.46150 0.03475 0.38407 0.06257 0.09422 0.01535
